Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

CSU has a JCI Metasys campus wide Building Automation System controlling in excess of 24,000 points including space temperatures based on space occupancy, time of the year, CO2 concentration, etc.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

The Campus-Wide Energy Conservation and Management Program included an exterior LED lighting upgrade project which provided for complete retrofits and replacements of parking lot lighting, parking garage lighting, and walkway and sidewalk lighting throughout the entire campus, totaling nearly 1,700 new exterior LED fixtures. In all, this project changed the quality and efficiency of lighting systems in 5 covered parking garages, 10 surface parking lots, and more than 2.5 miles of walkways, sidewalks, and plazas. As a result of this project, an estimated 75% of all exterior lighting on the 85 acre urban campus has been converted to LED. This project resulted in utility savings, increased efficiency and improved optical control. As a result, CSU’s electrical load decreased by 196,000 watts with a total reduction in consumption of over 1 million kilowatt-hours, a 54% reduction in usage over the previous lighting technologies.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

The CSU Administration Center utilizes geothermal heating.


A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

CSU invested $52M in energy conservation measures such as LED lighting, high efficiency fume hoods, and HVAC upgrades as part of the Campus-Wide Energy Conservation and Management Program. This program is entirely self-funded through guaranteed energy and maintenance savings.

Energy misers installed on vending machines reduce electricity consumption of the machines by 41% annually. 70 energy misers were installed during FY 2016. They utilize occupancy sensors to power down the machines when the surrounding area is vacant thus reducing operating costs and greenhouse emissions.
